Both of these Grapes library lamps, circa 1906, were assigned the same model number (No. 348), although they are very different from each other. Grapes on the left is more complex than the simple and stylized version of Grapes on the right.
Tiffany's leaded-glass lamps were introduced in the late 1890s and were instantly popular during this time when the upper class was hungry for fashionable goods to decorate their homes. This Wisteria library lamp is circa 1901.
Louis Comfort Tiffany not only designed and created leaded-glass windows in the early 1890s; he also produced lampshades made of blown glass. In addition to flora, Tiffany's shades also depicted various types of fauna -- bats, fish, peacocks, butterflies, and dragonflies. This is a detail of the Dragonfly reading lamp, 1900-1924.
In 1879, Thomas Edison developed a carbon-filament lightbulb that produced a bright, warm amber glow. Decorative lamp screens became a popular accessory for reading lamps to shield the eyes from the glare of this new type of lightbulb. This is a detail of the Moth lamp screen, 1900-1910.
The Dragonfly hanging shade is one-of-a-kind, most likely a special commission for a wealthy patron. The dragonflies in this hanging shade are more stylized and less realistic than the Dragonfly library lamp (1900-1910), yet wonderfully effective.
The individual blooms of a laburnum tree (on right) are small and relatively uniform in color. They grow in hanging clusters that greatly taper at the bottom. To accentuate this, Tiffany gave the shade an undulating form with hanging clusters to provide a realistic interpretation of the laburnum tree in bloom. This is the Laburnum library lamp, 1900-1915.
